3D profiler promises micron-level accuracy

22 March, 2013

Cognex has developed a 3D laser profiling system that provides readings in real units of measurement with micron-level accuracy, making 3D applications easier to understand and deploy. The system can perform inspections that would be too difficult for traditional two-dimensional machine vision systems.

For example, the DS1000 sensor (above) can:

• read embossed or raised characters;

• verify the presence of low-contrast items in boxes or packages;

• identify surface defects and chips with no or little contrast;

• measure heights and tilts of components to determine misalignments; and
